HKS 02-07 WRX / 04-07 STi Bellmouth Downpipe


Product type: Downpipes

Vendor: HKS

Tags: 02-07 WRX, 04-07 STI


This is a 3" catless downpipe with a cast bellmouth design. It is constructed from polished SUS304 stainless steel piping and is mandrel bent for the smoothest flow. An upgraded downpipe coupled with tuning is definitely one of the best ways to increase power. 

Because this product replaces/removes an OEM emissions control device we must state that this catless downpipe is for offroad use only.
